lcm(85, 30) = 510. 85 = 5 x 17 30 = 2 x 3 x 5 lcm = 2 x 3 x 5 x 17 = 510
17% of 30 pounds = 0.17 x 30 pounds = 5.1 pounds
5x - 17 = x + 7 4x - 17 = 7 4x = 24 x = 6 Check it. 30 - 17 = 13 It checks.
Do you mean (-6 x 2) - (17 x 30)? Same as (-12) - 510, or -522
x - 17 = 30+17 +17 (add 17 to both sides)x = 47

5 x 6 and 3 x 17
No. x-14 = 17 means x = 31. Add 14 to both sides of the equation to see this.
